`Application led September 8, 1913. Serial No. 788,74 i.

, and' State of Wisconsin, have invented certain new and useful Improvements in Concrete-MixerLoading Buckets, of which the following is a specification.

.The present invention appertains to the 104 artl'of concrete mixing machines and comprises essentially certain novel means for acilitating -the charging of the mixing drum Aof mixers of the above class with the materials which are to be mixed thereby.

`lli i While the invention -isparticiilarly designed and preferably operated conjointlv `with a mixingmachi'ne, it will be understood that the improvements hereinafter set* forth are susceptible of employment for general .l0 4purposes in ,charging or loading a receptacle or the like. y y

In the practical embodiment ofthe invenltion,it is contemplated to utilize a charging bucket made in two sectionsgoiie of which,

26 the delivery section, is suitably pivoted to a supporting frame, andthe other of which, a receiving section, is pivotally 'connected .with the delivery section for movement relative thereto' and for movement therewith. l0 Included intheinvention are specialhoist- `in means controlling the raising and low.

ering movement of the charging) ucket, pe-

culiar means formounting the sup rt, and a bumper for relievii'nfg the bucket to the .positionin whi ceivea load of materials for subsequent dis charge thereby` f u .s In the accompanying drawings, Fi re 1' is a side elevation showinga char ng ucket and coperating supporting an operating instrumentalities constructed in accordance wigi the ntial features of the invention; an y y y i el i Fig. 2 is a` front elevation-.of the bucketi y and certain parts of the hoistinghmechanism,

the frame and-truck upoiiw ic vis mounted being omitted.

. In the drawings, A designates a l0 any suitable construction and .pieferabl one such as ordinarily` carries the mixing um B and associa frame-work- 1n which the drum B is 5B mounted extends upwardly from said drum tached to its upper ucket upon the "Section D of the ,sheaves 7 andvlO 'it the op the to t e fact that w .ien the bucket is uprai 1 -Aintofits dotted 11i ie position shown at a: in driving mechanism of a` conventional Aof `concrete mixer. TheV "nected in a manner hereinafter' more fully 60,

described. Near the lower portion of said framework C are supplied ollstanding brackets 2 carrying a pivot 3 Vforming the axis uponfwhichtlie bucket D is mounted for bodily movemen' i.

The bucket D com prises an upper delivery section D` and the lower receiving section D, both of said sec tions tapering upwardly toward the receiving opening of the mixing drum B as shown most clearly on referencek to Fig. 2. The de 4ivery section D of the bucket has an arm )r casting 4 suitably atand and connected to the brackets 2 by the pivot 3 aforesaid. The lower receiving section D" of` the bucket is of an lar shapeis seen in AFig. 1 and is hingeV at va point intermedia-te its inner the innerend of tie section D upon `upward movement of said section is adapted to move relative to the section D extending partially into the latter, so as to insure the proper passage of the contents of the firstmentioned section into the delivery section D in the loading or `charging operation.` Secured -to the op posite sides 0j the lower 4 bucket are .the hoisting 90 cables 6 which pass -`upwardly over,` the sheaves 7 mounted on t c pivoted arms 9 carriedby the upf ermost portion of the de` livery section D. The trunnions 8 form the axes `of-arms 9 wfiich. are connected there- 95 with between. their ends and carry the osite ends, said sheaves 10 engagir g the cab es 6 on the sides 'of thela-tter opposite vthose at which the sheaves 7 are local ed. In `other words, each *cable 6 passes between an adjacentpair of zthe sheaves 7 and 10 and the sheaves` 10V are movablebodily with lthe arms 9, independentl of their rot ition on said arms owisi sobs y the latter not'being Ation D into the mixing drum. On reversing .tion DI rests upon the Y l truck A and thereafter thefsection D moves .comprising a curved strength with which the inner end of .the

to wind'. The hoisting of the bucket D is accomplished by operation of the winding shaft '1 which 1n addition to carrying' the drums 11 has also fixed thereon a main drum 12. A drivingcable 13 is connected with the drum 12 and passes therefrom to any suitable controlling and coperating mechanism,

` described, because immaterial in so far as the present invention is concerned, since any operating mechanism mag be employed foractuating the shaft 1. aving. in view the foregoing, it will be understood that with parts arranged in the full line position shown in Fig. 1, aterra load of materials has'been dumped upon the bucket section D" the cable 13 or equivalent means will `be operated .to raise the bucket.. Upon initial movement of the" cable 13 the cables' 6 are wound around' the drums 11 and the bucket ,section D is raised by pivotal movementlat the hinged po'ints `5 until the inner end of said section practically abuts with the bottom of the sec'- tion'D and until abutments 14'. in the form of angle plates on the sidesfofthe section D abut with the lower end o'f said section Preferablythe lower end offsaid section .l is provided atiopposite sides with the angle plates or plates 14 just mentioned. :The bucket section D",moves independently of the section D until said section D", reachesthe dotted line positiondesignated y in Fig. 1 .whereupon `the further movement of thecables 6 causes the two bucket sections to move lipward to their discharging position by simultaneous movement. In dumping it is evident that the contents of the bucket section D"'"pass therefrom through the delivery secoperation ofthe movement of the cable. 13 t() lower the bucket, the two sections move together until the upper secadjacent end of the on downwardly to its full` lineposition in Fig. 1. To retard the final movement of the sections Dfand D a/bumper 16 .is interposed between the adjacent end of the truekAfand the inn` lr and outer ends respectively o'f saidbucket sections, .said binnperA section D is adapted to abut asI it drops to.l

vtaneously engaging the Sectio D. I.

When the bucket' of the vmadbfrfle is not be- 4 ingl used the bucket section D tothe dotted-'line posltion 1/ 1n Fig. 1 and' the members D and D together,

atter elevated from the ground and the con ecting the l v 15 to engage the abutments @hauling the bfcktspring .y of suitable 7 t l l (nient vof vits extreme lower position, the springvsimulthat it is compressed by the section D as the latter drops-and the free end of the spring is forced upward to engage the sectlon as it reaches the truck.
